To RedRider -
these are great sites - I started with them too -- some long years ago ...
I have some photos of somewhat old and a little rustyCoastguard Life boat - MLB 44 feet -

those. who cares ..
If you have any links to the modeling site, I recommend - please browse through the offer of their topics .. yourself best know what you are interested. Excuse me .. you can also find many articles here too , on Modelboats => How to .. and this is where you should start.
I also recommend the reverse procedure .. enter the topic you are interested in - and Uncle Google will print a series of links ... search and answer ... if that's not what you're interested in - try to ask in another way .. when I started, it took me at least 3 days before I got the right answer to my specific question ..
Beware - you always have to take into account that Uncle Google has a "classic" education, and its technical knowledge is ... in many cases - say - minimal or curious.

Hi Red - they are separate websites - to find Google them - Mayhem is a UK site and RC groups is based in the US.

....so, where do I find "Model Boats Mayhem and RCGroups"? Are they a subgroup within this site? Thanks for any help.

Would agree.
Model Boats Mayhem and RCGroups are both mines of information.
Neither has a very easy "Search" facility, but once you get the knack of it both sites are well worth researching.

Hi,
I really recommend reading the articles in Model Boat Mayhem . In any case, you will find answers to your questions - even those that might interest you in the future.
I think those articles will certainly be of interest to experienced modelers - you can always find something interesting..
Ahoy !

Tom, thanks for your details. When first playing with these motors, I did figure out the Right turn vs. the Left turn of the screws, so, I thank you for insuring.
I will check out these links.
Cheers Mate!

Deciding on a battery depends on several factors. What is the expected current draw; the sailing duration and the battery weight etc? The model displacement and dimensions also affect battery choice.
Would think a 12v SLA cell of about 4/5Amphour capacity will give well over an hours running. This would typically weigh about 26oz.
Suggest that model will end up around 15lbs total weight as it is a displacement hull. Should be able to fit that capacity battery easily.
Sometimes better to get a couple of smaller batteries and wire up in series. Then you can move around to suit stability.
Once the hull is sealed suggest put it in water, mark the approximate waterline, locate the motors etc and then experiment with weights to estimate what is needed to immerse to the waterline, then choose a battery that works best.
Chances are you will require ballast too.

Hi,
Of course, one battery is enough, the output wires from the esc connect both engines in parallel - but you have to test the sense of rotation. If you have 2 engines on the model, then one must be right-handed and the other left-handed. I hope I'm not mistaken now. (see article from MBMayhem).
Try the motors first somewhere on the table, connect the wires directly to the battery (or 12V power supply - eg 12V car battery charger)
if you put a bow-oriented model in front of you, then the engine on your right hand must turn to the right (like tightening a screw), and the propeller must be clockwise - and drive the model forward. The engine on the left hand must rotate to the left, and must have an anticlockwise propeller. here you have to be careful and secure it because it tends to unscrew from the shaft.
After testing the motors, connect the wires of both motors to the output of ESC and
 - wires from both motors to - output from ESC. (servo do not have to deal with, compared to motors it has minimal power consumption)
yeah - you see - the ESC must be bidirectional - with zero position in the middle. this ensures that you can drive the model back and forth. ESC for aircraft models are unidirectional - they do not change the direction of rotation of the engine.
This completes the connection of the motors, you need a battery - you have to choose according to voltage and load (what current will the batteries draw while driving--
TOM
I can recommend too > https://www.modelboatmayhem.co.uk/Common/Electrics/Twin_motors.htm
forewords.. > https://www.modelboatmayhem.co.uk/Common/Electrics/1electrics.htm

Tom, as a NOOB, I think you are 100% as to one ESC. Later when my (feet /rudders) are wet and I have more experience, I can dabble in twin prop control.
So now, it looks like I need 12V batteries. Can one battery power this simple(r) system? That is, one ESC, two 12V motors and one rudder servo.
Thanks!

Hi,
you have two options - 1 Esc for both engines, control (usually channel 3 -Throttle) and steering the model using the rudder. I think this arrangement is easiest for you. Steering - rudder channel 4.

There is a second option, control by changing the speed of the left or right engine. You need 2x ESC (for each motor) and mixer (for mixing control channels). I use this to control the Lulonga paddle steamer model - the rudder model has little efficiency. Mixing channel 3 -Throttle +channel 1 - Ailerons (right stick)
I control the model with only one stick.I had less difficulty programming the mixer in the transmitter, so I used the V tail mixer.-No problems .(http://www.paddleducks.co.uk/smf/index.php?topic=6336.45 )
- Left stick- - channel 4 -rudder ,channel 2 + siren, - foghorn .
Ahoy!

Tom

From the pictures, they are brushed type motors. If so, one ESC can control both and they will operate in unison.
If you want better directional control, use two ESCs. That will allow one propeller to go ahead and the other astern independently - if your transmitter will allow.
With a lever style transmitter (Tx) you can put a motor on each lever and use the up/down action to impart fwd/rev motion to that motor.
If your Tx will allow "Elevon" control both motors can be put on the same lever. Moving the lever up will direct both motors fwd, similarly down for astern. Moving to one side controls one motor and the other side, the other. Find this mode ideal for all my twin screw models.
Other contributors have used a "Mixer" which combines the two motors response with rudder action.
Have never used this as the Elevon operation suites me.
Plenty of food for thought. First thing though is to get everything going as simply as possible, so you know it works.

These were taken when setting up the mounting system.
Btw, it appears from the wiring schematic posted (Tomarack) If I want to have more steering control from these motors, I'll need two ESCs, one for each motor. Am assuming this would allow for "push / pulling" of the props, all other aspects being correct? Just guessing.

You could post a picture to help confirm.
Most likely brushed though, brushless are not as popular

Thanks Mate, super big help. Looks like mine are brushed. It’s baby steps, however, am moving forward.

Generally:
😁Brushed usually have two wires and brushed three. The brushed are often the same colour, the brushless colour coded red,yellow and blue/ black.
There are exceptions but not often.
Brushed can also operate if touched to a small battery, brushless need a speed control.

Hi Guys,
I lifted off the Dumas site.
For those that don't know It's A Coastguard Life boat.
Length 33 inches
Beam 9 inches
Scale 3/4 in. to 1 ft.
At this point, It's completed to the point of requiring running gear. The hull is finished, but, needs it's water proof coating.

My motors (twin screws) are 12V and have the proper RPM, but, I don't know if they are brushed or brushless. They were given to me. I'm waiting on my ESC from Dumas.

I have migrated all my models to Li-Po. They have good power density and are relatively light, use them on fast Patrol boats.
They DO need treating with respect and charged and maintained carefully.
If used properly they are great.
I always use a fuse in each ESC main lead. Problem is a fuse around 40A + is often needed and they are awkward to fit.

I like the diagram as well but where is the fuse.

Regarding Lipo batteries, I have used them on rc airplanes because they are lightweight. However on boats, I prefer Nimh or SLA's as the weight is not an issue, and ballast is usually needed anyway. Lipos can be very dangerous if not carefully charged and maintained, many fires have occurred do to misuse.

One of our sailng club members burnt his garage down because he left Lipos unattended during charging. Lost his entire collection of boats. I got rid of all of my lipos and will not have them in my house, not worth the risk for use in boats.

Just my opinion, Joe

Absolutely agree Tom
That's an excellent basic set up diagram for the beginner 👍

"If one has many years of experience with RC models, he does not even realize what problems a complete beginner has to solve,"
Exactly. You can see this effect sometimes in the answers here.
Thirty odd years of designing ship communications systems, and then writing the system description, quickly taught me to look at the subject from various perspectives-
1 For the Admiral; who may have no comms or engineering experience and simply wants to know: What can I do with this system? Why should I spent my hard fought budget on it?
I.e. Cost versus Operational benefit.
2 For the naval crews and engineers who have to operate it and maintain it.
3 For the shipyards who have to install it and 'sell' their whole ship package to the navy.
The first time I fell into the 'experience' trap you mention taught me a BIG lesson!!
Lost contract😭
All the best, Doug 😎

My advice is read about LiPo batteries before doing anything with them. They are really superb batteries, I have lots, but they need to be charged and discharged with care. A special balance charger is required and monitors for capacity per cell etc. They are really good batteries, but as a beginner, treat them with great respect and read all documentation before using them. Do not let this put you off, just get the information first. Additionally, always put a fuse in the circuit.
Thanks.
Peter.

Hi Doug,
as you can see, giving advice is often problematic. If one has many years of experience with RC models, he does not even realize what problems a complete beginner has to solve, especially when he is not familiar with at least the fundamentals of electricity and the operation of the various components that are used.
It reminds me of a modeler who did not build a small boat, but immediately begins building Nelson's Victory with 100 cannons. Usually it ends infamously and with disgust - and with aversion to ship modeling.
That's why we try to help, but as you write, it is really not possible without basic information.
Ahoy!
Tom

Hi Herr RNinMUnich.....
Thanks for your informative and helpful comments. Your questions cause me to "dig into" my homework.

Hi Tom
"it is difficult to advise remotely when we do not have information ..."
Hoorah hoorah hoorah! You are SO right Tom.👍
We often get cryptic enquiries which are a bit like asking "How long is a piece of string"🤔
Some basic info about the model and intentions with it, as well as about available electrical / electronic components helps enormously. As do a few photos.
Cheers, Doug 😎

" together with a number of my contacts on those forums have put together "stickies" that new guys can view for learning the basics of that world. Perhaps here, the more knowledgeable can do the same? "
Funny you should mention that RedRider,
I was just pondering exactly that after reading your answers here.
In the meantime have a look in the section 'How-To-Articles' on this site.
See Main Menu on the left.
There's lot of info on the basics of RC for boats/ships already there.

The basic initial info we need to help further is-
1 We know the type of boat but-
- Scale? How big is the boat' LoA?
- Weight / Max Load it can carry?
Test in the bathtub (Domestic Test Tank😉) before any motors or batteries are fitted.
2 We know which TX/RX set you have but-
- Which ESC, Maker and model/part number?
3 Which motors?
- Brushed or brushless?
- How many? Single or twin screw? Or?
Photos of the various components you have tell thousands of words and help enormously👍
Cheers, Doug 😎

Thanks for your reply. Being new to the RC electrics, I don't know what information is needed to ask. I'm just now learning the basic diagram of how some of the basic the components go together and the associated terminology. My ignorance is very telling in this area.
I'm well versed in classic vehicle restorations and together with a number of my contacts on those forums have put together "stickies" that new guys can view for learning the basics of that world. Perhaps here, the more knowledgeable can do the same?

Hi,
it is difficult to advise remotely when we do not have information - what engines do you have? - brushed,or brushless?? , what voltage, what ESC, what servos?
Selection is based on electric motors, according to which ESC (electronic controller) and batteries are selected ( LiPo,LiFe, Pb, NiCd).
In every ESC package you have a manual with all the components involved. So please read it carefully and connect the individual components accordingly. If there is no manual, so you will find it on the Internet by manufacturer and type.

On the Internet you will find a number of manuals that deal with RC models. There you will find a number of good advice clearly written. It is always recommended to start from the simplest models with simple operation. Try to find an experienced modeller somewhere near your home, who will specifically advise you.
Thus, you should probably start as the first option.
Attached is some connection options - on the net is more .. just a look ..
As for the transmitter, the engine (ESC) is controlled at the throttle position, the other servos you plug into the positions that suit you. Usually, it is possible to select a combination of channel positions on the transmitter that correspond to the positions of the controlled channels on the receiver.

wishing success
Tom

[quote]Can it be used for boats too?[/quote]

Yes, 2.4 ghz can be used for rc boats.
The transmitters search for clear frequencies in the spectrum each time you turn it on.
So there will be no issues with interferance.

Be sure to keep the receiver antenna above the water line, and you should be fine.

😊

Thanks Mate, big help in understanding all of this.......
Can I assume, the wire end connectors are standard? That is, for connecting those components that connect to the Rx? I understand the "LiPo" batteries are the way to go. I have two prop motors, first, I need to clarify their voltage (6 or 12v). What considerations do I need to know in choosing the Ah of the batteries? How many components will I be installing?

Hi,

I don't believe you can reprogram the switches. - What would you like to be able to use the switches for?

Had a quick looks and this is a 6 channel TX - 4 channels taken by the 2 sticks - that leaves 2 channels between 3 switches.

I would think that you have a 2 and a 3 position switch and the other is a mix/mode/rate selector.

Looking at the 2 switches these could be used within the boating world but are not proportionally controllable like the 4 channels on the 2 control sticks.

The best way to get a feel for what the 2 switches & associated channels do is to connect a spare servo and then move the switch.


Regards
Jonathan .

Hope someone can clarify something for me. I have a Hitec Optics 6 Sport TX. I have been informed that the switches Ail/Elev/Rudd on SW2 (top right hand corner) and Gear/Flt mod ST-3 on SW1 (top left hand corner) as well as the 3 way switch Flt Mode (SW3)are not able to be reprogrammed to suit maritime type functions usual on RC boats
I would be delighted if someone could advise me to the contrary...and if so how to set about reprogramming those controls.

Hey Guys,
Ok, thus far I have a TX, TR, (does this stand for receiver?). I have a speed controller (w/BEC) on order. I still need a rudder servo and battery(s)
AM assuming the motors are connected to the speed controller? The rudder servo is plugged into the receiver?
Now, what do I need to know when looking for batteries? Will I need more than one? Haven't planned on any lights or accessories, at least, for now,
Just seeking to getting what's needed to get the props turning by RC.
Thanks for any details.

Thanks Mate!

Red rider,
Back to your original question on the DX5e. I have this tx, it comes from a airplane simulator package that I bought years ago. Two weeks ago I pulled mine out to try it on my rescue Tug, works just fine. It's just a basic model, doesn't have a lot of frills for complicated programming but for boats it works fine. I like the simplicity of it.

Let me know if you have any specific question or problems with yours and I can help you from this end.

Joe (USA) 👍

Ok, I have a plan.......
I ordered a speed controller from Dumas, as a start. Am planning to get a couple of servos and a battery. Once I have what, I think, I need I'll build a styrofoam swamp boat as a training exercise. We'll see....

Thanks Mate, but, it's a keeper! It's in my possession....
Am looking forward to "leaning" on my mates here fo help.

Sounds like a plan RR 👍
Let us know how it goes.
Cheers, Doug 😎

Since, I’m new to the RC electrics, I’m going to put together a test sled similar to a swamp hover craft. Add a simple servo, motor with a prop, speed controller, ESC, and battery. Learn the techniques of how it all works. I don’t think, this Trans & receiver has been used, as the batteries were still in their original packaging.

Ok, Guys thanks!
